Find parametric equation for ellipse

  1. Jan 27, 2012 #1
    1. The problem statement, all variables and given/known data

    Find parametric equation for (((x-2)^2)/4)+(((y+1)^2)/9)=1

    2. Relevant equations

    ((x^2)/(a^2))+((y^2)/(b^2))=1 (ellipse equation)


    3. The attempt at a solution

    I tried solving for y which gave me y=(6/(x-2))-1, but that did not work.

    hi getty10! :smile:

    hint: an ellipse is a squashed circle

    what parametric equation do you know for a circle? :wink:
